ఇచ్చినది

P(3) = P(4)

భావన:  

పాయిజన్ డిస్ట్రిబ్యూషన్=ఇది డిస్క్రీట్డిస్ట్రిబ్యూషన్ కూడా 

పాయిజన్ డిస్ట్రిబ్యూషన్ నామమాత్రపు పంపిణీ పరిమితిని పూర్తి చేస్తుంది. 

పాయిజన్ పంపిణీ  f(x) = (e-λ × λx)/x! 

x = 0, 1, 2, 3---- మరియు  λ = సగటు 

లెక్కింపు 

ఇక్కడ x = 3 and 4

⇒ (e-λ × λ3)/3! = (e-λ × λ4)/4!

⇒ λ  = 4!/3!

⇒ λ = 4 

∴ పాయిజన్ డిస్ట్రిబ్యూషన్ లో x యొక్క సగటు 4
